LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 406,813, dated July 9, 1889.

Application filedAugnst 14, 1888. Serial No. 282,754. (No model.)

To ctZZ whom it may concern.-

Be it known that I, BENJAMIN A. BURGESS, a subject of the Queen of Great Britain, and a resident of London, in the Province of Ontario, Canada, have invented certain new and useful Improvements on Lubricators, of which the following specification, taken in connection with the accompanying drawings, forms a full, clear, and exact description.

This invention consists of the improved construction and combination of parts of the same, as will be hereinafter first fully set forth and described, and then pointed out in the claims, reference being had to the drawings already mentioned, wherein- Figure 1 is a front elevation of alubricator embodying my invention. Fig. 2 is a side elevation of same. Fig. 3 is a vertical sectional view on the line a a of Fig. 2. Fig. 4 is a vertical sectional view on the line 00 0c of Fig. 1.

R designates the oil-reservoir for holding the oil or other lubricant, and R is a chamber in'this oil-reservoir R,-which is separated from the lubricant in said reservoir by a partition R i S is a hollow stem, which is secured at one end to the oil-reservoir R. The other end of this hollow stem S is to be secured to a steamchest, cylinder, or to a steam-pipe leading to a steam-chest, cylinder, or other part requiring lubrication, (not shown,) into which the hollow stem S opens, as well as into the chamber R This hollow stem S permits the steam to pass to the chamber R thereby heating said chamber R for the purpose of heating and disintegrating the oil or other lubricant, so that it will flow regularly and perfectly free from the oil-reservoir R.

T is a tube secured at one end to the hol- The other end of this tube T is secured to the ante-chamber B, and this tube T opens into the hollow stem S as well as into the ante-chamber B. This ante-chamber B is secured to the condensing-chamber O and this ante-chamber B opens into said condensing-chamber O T is a tube secured at one end to the condensing-chamber C and at the other end to the oil-reservoir R, and this tube T opens into the oil-reservoir R as well as into the condensing-chamber G a The tube T permits the steam to pass from the hollow stem S to the ante-chamber B, and from the latter the steam passes into the condensing-chamber O where the steam is condensed.

V is a valve, which is operated by the handle V, and this valve V is situated in the lower part of the condensing-chamber G which valve prevents or permits thecondensed steam or hot water to flow in any desired quantity from the condensing-chamber G into the tube T, and from the latter this condensed steam or hot water flows into the oil-reservoir R.

The object of providing the ante-chamber B is to form an abutment for the steam to strike against to break the force or flow of the steam and to give it a rolling motion just as it enters the condensing-chamber O This breaks the force or flow of the steam to prevent it from displacing the condensed steam or hot water in the lowerpart of the condensing-chamber Ciwhereas if this steam entered the condensing-chamber C in a steady flow or jet it would have a great tendency to strike one side of the condensing-chamber and pass under and raise the condensed steam or hot water in the lower part thereof. This would prevent the condensed steam or hot water from passing regularly and evenly into the tube T and oil-reservoir R, which is necessary in order to cause the lubricant to flow regularly and perfectly free.

B B are brackets, each of which is secured at one end to the oil-reservoir R, as shown in Fig. 4', and G is a glass tube supported between the brackets B B and this glass tube G is secured to said brackets by the nuts F F. P P are passages in the brackets B B The passage Pin the bracket B opens into the glass tube G and into the oil-reservoir R, and the passage P in the bracket B opens into the chamber R as well as into the glass tube G.

V is a valve, which is operated by the handle V and this valve is situated in the bracket B to prevent or permit the lubricant to pass from the oil-reservoir R in any quantity re quired.

The operation is as follows: The steam from the steam-chest, cylinder, or steam-pipe leading to the steam-chest, cylinder, or other part requiring lubrication (none of which is shown) passes into the-hollow stem S, and from thence it passes into the chamber R for the purposes hereinbefore specified. The steam also passes into and through the tube T and from thence into and through the ante chamber B, for the purpose hereinbefore specified, and from thence into the condensing-chamber G which has a large surface for the purpose of condensin'gthe steam. The condensed steam or hot water flows into and through the tube T and into the oil-reservoir R. As this condensed steam or hot water flows into the lu- "bricantreservoir R the lubricant contained therein is raised to the passage P in the bracket B, through which it flows, and from thence through glass tube G, bracket B chamber R and hollow stem S to the steam-chest, cylinder, or to a steam-pipe leading to the steam-chest, cylinder, or other part requiring lubrication.

If the valve V should be regulated to permit only a very slight flow of lubricant from the lubricant-reservoir R, the condensed steam or hot Water may become cold in the tube T; but as soon asit enters the oil-reservoir R it comes in contact with the partition R of the steam heated chamber R which speedily raises it to a high temperature, and the action of the heated water on the lubricant has the effect of rendering or clarifying the oil or other lubricant in the oil-reservoir R.

W is a waste-cock at the side of the lubricant-reservoir R, which permits the accumulating water of condensation to be drawn off before refilling said reservoir R with lubricant.

A designates a brace, which is secured at one end to the side of the tube T. The other end is flanged and secured by a screw, A to the side of the oil-reservoir R. This braces and firmly secures the tubes T T and condensingchamber 0 in an upright position.

Having thus described my invention, I claim 3. A lubricator comprising an oil-reservoir R, a steam-heated chamber R within said reservoir and separated from the lubricant contained in said reservoir by a solid partition R a hollow stem S, the tube T, antechamber B, condensing-chamber C valve V, and tube T, substantially as shown and described, and for the purpose specified.

4. A lubricator comprising an oil-reservoir R, hollow stem S, the tube T, ante-chamber B, condensing-chamber 0 valve V, and tube T, in combination with the brackets B B having passages P P therein, respectively, valve V and glass tube G, substantially as shown and described, and for the purpose specified.

5. A lubricator comprising an oil-reservoir R, a steam-heated chamber R within said reservoir and separated from the lubricant contained in said reservoir by a solid partition R a hollow stem S, the tube T, antechamber B, condensing-chamber 0 valve V, and tube T, in combination with the brackets B B having passages P and P therein, re spectively, valve V and glass tube G, substantially as shown and described, and for the purpose specified.

In testimony whereof I affix my signature in the presence of the two undersigned witnesses.

BENJAMIN A. BURGESS.
